4.3.10 Certification of an engine family

  4.3.10.1 The certification shall include a list, to be prepared and maintained by the engine manufacturer and approved by the Administration, of all engines and their specifications accepted under the same engine family, the limits of their operating conditions and the details and limits of engine adjustments that may be permitted.

  4.3.10.2 A pre-certificate, or EIAPP Certificate, should be issued for a member engine of an entire family in accordance with this Code which certifies that the parent engine meets the NOx levels specified in regulation 13 of Annex VI.

  4.3.10.3 When the parent engine of an engine family is tested/measured under the most adverse conditions specified within this Code and confirmed as complying with the maximum allowable emission limits (see 3.1), the results of the test and NOx measurement shall be recorded in the EIAPP Certificate issued for the particular parent engine and for all member engines of the engine family.

  4.3.10.4 If two or more Administrations agree to accept each other's EIAPP's, then an entire engine family, certified by one of these Administrations, shall be accepted by the other Administrations which entered into that agreement with the original certifying Administration, unless the agreement specified otherwise. Certificates issued under such agreements shall be acceptable as prima facie evidence that all engines included in the certification of the engine family comply with the specific NOx emission requirements. There is no need for further evidence of compliance with regulation 13 of Annex VI if it is verified that the installed engine has not been modified and the engine adjustment is within the range permitted in the engine family certification.

  4.3.10.5 If the parent engine of an engine family is to be certified in accordance with an alternative standard or a different test cycle than allowed by this Code, the manufacturer must prove to the Administration that the weighted average NOx emissions for the appropriate test cycles fall within the relevant limit values under regulation 13 of Annex VI and this Code before the Administration may issue an EIAPP Certificate.

  4.3.10.6 Before granting an engine group approval for new, serially produced engines, the Administration shall take the necessary measures to verify that adequate arrangements have been made to ensure effective control of the conformity of production. This requirement may not be necessary for groups established for the purpose of engine modifications on board after an EIAPP Certificate has been issued.
